Beta-endorphin was measured in the plasma of pigs during late pregnancy and at different stages of the oestrous cycle. In pregnant animals, beta-endorphin secretion from uteroplacental tissues into the maternal circulation and the possible effects of oxytocin and the prostaglandin F2 alpha (PGF2 alpha) analogue cloprostenol on beta-endorphin release were determined. Plasma beta-endorphin concentrations in pregnant sows were significantly higher than in non-pregnant pigs. However, there were no significant changes in beta-endorphin values throughout the oestrous cycle. Because the increase in plasma beta-endorphin concentrations had occurred before luteolysis and onset of labour it could not be attributed to the stress of parturition. The surgical intervention of a laparotomy increased beta-endorphin release into peripheral plasma. Cloprostenol but not oxytocin caused an immediate increase in plasma beta-endorphin concentrations. At parturition, endogenous PGF2 alpha may be involved in the regulation of beta-endorphin secretion. Concentrations of beta-endorphin in the jugular and uterine vein plasma were not significantly different, and so it would appear that beta-endorphin in the plasma of pregnant sows is not of uteroplacental origin. In conclusion, changes in the concentration of beta-endorphin in peripheral plasma, associated with pregnancy but not the oestrous cycle, exist in pigs. Hence a physiological function of peripheral opioid peptides in the periparturient sow is feasible.
